Yokogawa releases enhanced ProSafe-RS safety instrumented system

Yokogawa Electric Corporation has announced that it is to release an enhanced version of its ProSafe®-RS safety instrumented system, the Prosafe-RS R3.02.20 on 26 December.

The new system offers improved connectivity with the ProSafe-SLS SIS, enabling the status of systems to be monitored on screen by operators of the CENTUM® VP integrated production control system. In addition, R3.02.20 offers enhanced support of widely used open communication protocols, improving connectivity with other companies’ SCADA (supervisory control and data acquisition) software.

Overview of enhancements

Integrated monitoring systems

With the ProSafe-SLS information gathering capability on Prosafe-RS SIS, operators can now monitor the status of a ProSafe-SLS SIS from Centum VP window. If a problem occurs anywhere in a plant, the sequence of event (SOE) data from both SISs will be displayed on an integrated screen at the operator terminals. Operators and maintenance engineers can then use this data to quickly identify and analyse the problem cause.

Communication protocol support for upstream applications

In oil and gas wellhead and pipeline applications, cost performance and space savings are key considerations. To satisfy these needs, ProSafe-RS is equipped with both safety and process control functions. The SCADA systems at such sites often rely on Distributed Network Protocol 3 (DNP3) for narrowband wireless and satellite upstream communications because this open protocol supports the temporary storage of data when there is a disruption in network communications. Support of DNP3 in the ProSafe-RS R3.02.20 controller enables customers to easily replace and expand their systems in the field while continuing to use their existing SCADA infrastructure. This saves time and reduces costs.
